ADJUSTABLE RADIATION REFLECTOR (ALTERNATIVES) Russian patent published in 2002 - IPC

FIELD: space engineering. SUBSTANCE: adjustable reflector has air chamber made in the form of rectangle engageable with mirror sheet whose non-reflecting surface is covered with isolated magnetic-film strips in which orientation of magnetic fields of force (N-S) are alternating. Reflector may be provided with helical conductors deposited in parallel to each other onto air chamber, first helical conductor being connected to first emf source and second one, to second emf source through double- pole switch. In addition adjustable radiation reflector may have parallel conducting strips deposited in zigzag manner onto non-reflecting surface of mirror sheet so as to ensure opposing currents in odd- and even- numbered strips.. EFFECT: enlarged size of rectangular mirror surfaces. 3 cl, 3 dwg
